java support for tiff and other image formats

Java ImageIO supports most common image formats like jpeg,png,gif,bmp etc..Tiff format is not one them.This caused some inconvenience when I was working on a face recognition app that uses tiff images from the JAFFE image database (http://www.kasrl.org/jaffe.html).So I had to use plugins from jai-imageio .To check availability of image readers for various image formats,I modified the code in my previous post slightly.
...
public static void checkImage(String name) throws IOException{
ImageInputStream imgInStream = ImageIO.createImageInputStream(new FileInputStream(name));
Iterator readers = ImageIO.getImageReaders(imgInStream);
if (readers.hasNext()) {
ImageReader reader = readers.next();
System.out.println("At least one image reader exists for "+name);
System.out.println("image reader ="+reader);
}else{
System.out.println("No image reader exists for "+name);
}
}
public static void printAllSupportedImageFormats(){
String[] names = ImageIO.getWriterFormatNames();
System.out.println("supports "+names.length+" formats");
for ( String name: names ){
System.out.print( name +" ");
}
System.out.println();
}
public static void main(String[] args) throws IOException {
printAllSupportedImageFormats();
String img1 = "/home/sajan/Pictures/Bounty_Ship.jpg";
String img2 = "/home/sajan/Pictures/PGPHX82.GIF";
String img3 = "/home/sajan/Pictures/abe_natsumi.ppm";
String img4 = "/home/sajan/Pictures/abe_natsumi.pgm";
String img5 = "/home/sajan/images/JAFFEPRB/KLH158.tiff";
String[] imgs = new String[]{img1,img2,img3,img4,img5};
for (String img : imgs){
checkImage(img);
}
}

...
Using standard ImageIO,I got this result...

supports 12 formats
jpg BMP bmp JPG jpeg wbmp png JPEG PNG WBMP GIF gif
At least one image reader exists for /home/sajan/Pictures/Bounty_Ship.jpg
image reader =com.sun.imageio.plugins.jpeg.JPEGImageReader@1f42b49
At least one image reader exists for /home/sajan/Pictures/PGPHX82.GIF
image reader =com.sun.imageio.plugins.gif.GIFImageReader@87a5cc
No image reader exists for /home/sajan/Pictures/abe_natsumi.ppm
No image reader exists for /home/sajan/Pictures/abe_natsumi.pgm
No image reader exists for /home/sajan/images/JAFFEPRB/KLH158.tiff

After adding jai-imageio-1.1.jar to the classpath,the result was...
